      Dr. Greger, have you considered the possibility that humans should only be taking in vitamin D from the interaction of the sunshine on our skin, that all forms of vitamin D that we pass through our mouth (both supplements and food sources) somehow might be disrupting some sort of internal homeostasis as far as vitamin D receptors, hormones, autoimmune regulation. Something seems amiss to me, the popping of pills and food and expecting the same exact reactions internally as that of the relationship of the sun’s rays and our skin. Are humans possibly playing god by popping pills? And is there a limitation and or consequence to this that might possibly be unknown to us?

    I have a question: what can be done for females to lower androgen hormones (androstenedione) ? I dont eat much fat, basically eat like you say in all the videos, been vegan (sometimes eat eggs from my chickens) for 10 years. I’ve been tested for PCOS and don’t have that. Im 26 now. are there any supplements that might help lower androgens in females?
